dentify the source of the following quote: "We must not divide the one Lord Jesus Christ into two sons [Son of God and son of man]. Nor is it sufficient for sound doctrine merely to hold a union of [two] persons, as some do [Nestorius]. For Scripture says not that the Word united himself to the person of a man, but that he was made flesh. That means nothing else than that he partook of flesh and blood like us. He made our body his own, not ceasing to be God."
